Insomnia at 34 weeks pregnant

Im 34 weeks pregnant and having a lot of trouble getting quality sleep. I have backaches sleeping on my side (even with pregnancy pillow and lots of pillow support) and feel alot pressure at the pelvic area if sleep on my back.. so theres no comfortable sleeping position.. plus i wake up between 5 to 8 times a night to pee (almost every 1 to 2 hour in the day as well) so the quality and quantity of my sleep has been really poor. It makes me so tired and unfocused in the day and my productivity at work has dropped too.. (i originally planned to work till edd but now Im considering taking HL earlier ..) any one has similar issue or advice on how to sleep better..?
